1N4001 rectifier

Description :

The 1N4001 is 50V, 1A, Recovery Rectifier. This diode is a general-purpose silicon rectifier diode that is commonly used in power supply circuits.


1. Diffused Junction

2. High Current Capability and Low Forward Voltage Drop

3. Surge Overload Rating to 30A Peak

4. Low Reverse Leakage Current

5. Plastic Material: UL Flammability Classification Rating 94V-0


Maximum Ratings and Electrical Characteristics:

1. Maximum repetitive reverse voltage: The 1N4001 diode has a maximum repetitive reverse voltage rating of 50 volts, which means it can withstand up to 50V in the reverse direction without breaking down.

2. Maximum forward current: The 1N4001 diode can handle a maximum continuous forward current of 1A, making it suitable for a variety of low to moderate power applications.

3. Maximum surge current: The diode can handle a maximum surge current of 30A, which means it can briefly handle high current spikes without getting damaged.

Why use 1N4001 diode instead of 1N4007 diode

1. Lower cost: The 1N4001 diode is generally less expensive than the 1N4007 diode due to its lower voltage and current ratings.
Smaller size: Since the 1N4001 diode has lower voltage and current ratings, it can be made smaller and take up less space on a circuit board.

2. Lower power dissipation: The 1N4001 diode has a lower maximum power dissipation rating of 3 watts compared to the 1N4007 diode’s rating of 30 watts. This can make it a better choice for applications with lower power requirements.

3. Compatibility with lower voltage components: The 1N4001 diode’s lower voltage rating makes it a better match for components with lower voltage ratings, such as resistors and capacitors.

In summary, the 1N4001 diode can be a more cost-effective, space-saving, and appropriate choice for applications with lower voltage and power requirements.
